Many books say that autumn is golden, but it is clear that the people who invented such a wonderful word as golden autumn are not from Mincheng. Pen % fun % Pavilion www.biquge.info

At the beginning of August, the still warm wind blew through Lin Xi's small garden, and the surrounding fence trapped this place full of flowers and greenery, but it could not trap the people in the garden.

Lin Xi squatted on the ground and watched curiously as a cabbage worm crawled on a vegetable leaf, leaving a lot of jagged transparent holes behind.

"Stupid guy, why do you want to climb? Wait until you grow up and become a butterfly before flying away. ”

She grunted softly, pinched the green worm with her hand, and let the soft and cool sensation slip over the back of her hand, a little itchy.

Returning to the house with his hands on his back, he placed the green worm in a small jar with a net of mercury in the lower part, and the green worm struggled for a moment and finally had no chance to turn into a butterfly again.

After taking out the green worm, he skillfully took out a very delicate set of tools and cut open the belly of the green worm to remove the slimy internal organs. Dexterous hands skillfully kneaded a ball of white cotton into small strips, stuffed it into the stomach of the green worm, glued it to a piece of paper with soft glue, and placed it in a dry place in the middle of the house.

When she returned to the room, she took out a small hand-copied book given to her by Jian Chen a few days ago, with the cover written "Analyzing Geometric Problems with Arithmetic Methods".

This is something that has never been seen on the market, and it is all hand-copied content, and there is something called a geometric coordinate system.

This is a very good book, especially for Lin Xi, because many geometry problems that originally seemed difficult to solve can easily be answered in this way.

I received this book a month ago, it is written in great detail, and it is a simple explanation with a common Go board and the vertical and horizontal grids commonly used by people when playing chess, and Lin Xi can easily understand it.

It's just that the gratitude and happiness in his heart are difficult to share, Chen Jian hasn't appeared these days, as if he has disappeared, Lin Xi inevitably has something in his heart that he misses, always thinking about what he will say after meeting, but he can't guess it.

Faintly, she thought she liked the mysterious feeling of incomprehension.

But when the familiar voice calling her name outside came, she was a little panicked, hurriedly pulled her hair, and hurriedly glanced at the bronze mirror, only to find that she didn't know when the sweet smile had reached the corner of her mouth, but she didn't believe that what she liked was actually not the kind of feeling that she couldn't guess.

According to the old rules, let the people outside come in by themselves and make weak tea, this time not only did not have a gun, but also a few more rice cakes.

After Jian Chen sat down, Lin Xi picked up the tea, but didn't drink it, but stared at Jian Chen with a little weirdness as if he was smiling.

After being looked at for a long time, Jian Chen felt a little awkward, and subconsciously glanced at the clear tea to see if there was something on his face.

There was a silver bell-like laugh from the other side of the small table.

"Are you Jian Chen? Or Lei Zhengxing? ”

Jian Chen also smiled and asked, "You know everything?" ”

"I always have to go to the city, so naturally I heard some things, read some stories, and saw that my flowers were sold for dozens of silver coins a pot, and of course I knew what was going on."

When I thought of the story, I naturally thought of the widely circulated illustrations about mermaids, and when I thought of the enchantment and temptation in those reproductions, my face turned a little red and I took a sip.

"You wrote all those stories, just to sell flowers?"

"More than that."

Chen Jian took out a very beautiful invitation card and said, "Not only those stories, but also a scene." It's going to be a show tomorrow night, you can go see it with me, it's a good location. ”

"Play? It's also a play to sell flowers? ”

"Of course. I said, I'm going to sell it for a lot of money, and we'll sell it for half of each of us. What I promised you was selling flowers, but I didn't promise you to write stories and plays. ”

Hearing this, Lin Xi smiled and remembered these words in his heart, glanced at Jian Chen carefully, reached out to take the invitation, and looked at the strange name on it.

Frowning and staring at the word orphan in the four words, his heart was slightly sour.

My heart was sour, and my smile became even sweeter, and I pretended to be unintentional and said: "If it was the first time I met you, you said that you could make up stories, write plays, and do arithmetic and geometry, I would never believe it." ”

Jian Chen smiled cheekily: "In this way, you can remember deeply, so as not to forget it soon." ”

Lin Xi bit his lip lightly, his pounding heart and the thoughts in his mind mixed together.

"yes, I can't forget it." Thinking like this, he said, "This year is a strange year, and I can't forget many things, as if everything has become weird." ”

"Weird?"

"yes, at least for me weird. For example, when I met you, or because the stars of the earth did not circle around the sun, such as the huge bones dug up in the quarries described in the brochure, which were larger than elephants, and which had never been seen and did not have any legends. ”

Jian Chen felt that all this was normal, so he was very puzzled and asked, "What's so strange about this?" ”

"Have you ever heard the story of Pangu Kaitian left in ancient times?"

"Of course I did."

"If heaven and earth are really split, then it must be perfect. The earth should revolve around the sun in a circle, and the grass, trees, fish, insects, teeth, beasts, and claws should all exist from the moment the sky opens. The years are changing, but those animals and plants will not change. ”

"But now it's completely different. Isn't it strange enough that the earth no longer revolves around the sun, and that beasts have appeared in the quarries that have never been seen before? Where did everything in the heavens and the earth come from? It has existed since the beginning of the world? Or is it not the case, and maybe the world itself existed before man even existed? ”

"Originally, the world we knew was too small, so we didn't have to think about explaining the world. But now I've seen too much, and I have to think about it. Why is grass green? Why are flowers red? Why do deer run fast? Why do fish swim in water? ”

"The original explanation was the simplest, and when the world was opened, everything existed. But this explanation is no longer tenable, at least in my eyes. The simplest and most perfect, but the most perfect may not be right, just like the most perfect circle becomes an imperfect ellipse, but everyone has to accept it. ”

Hearing this, Jian Chen smiled and asked, "Then you like simplicity and perfection?" Or is it complex and imperfect? ”

"Of course I like simplicity and perfection, but the world itself doesn't exist because I like it or not. What I like is not necessarily real, but I want to know why there is such a world where thousands of red fish and birds fly more than personal likes. ”

"In fact, once I want to learn this, I am destined to be denied perfection. For example, crucian carp is spiny, begonias are fragrant, butterflies are actually caterpillars, and colored mushrooms are mostly poisonous, which my father told me about when I was a child. ”

Chen Jian nodded, and said, "Perhaps, it's actually perfect." Like you said, why is grass green? Why are flowers red? Why do deer run fast? Even why the flowers, grasses, fish and insects of heaven and earth are like this, there may really be a perfect set of things to support. It's just that we haven't found it yet, so it looks disorganized. It's like ......"

After thinking about it, Jian Chen finally came up with an explanation and asked, "Is there a needle and thread?" ”

Lin Xi knew what this was trying to explain, so he turned out the needle and thread.

I found a piece of paper, drew a line, tied two needles to the thread, separated the midpoint of the two needles, and tied a section of thread to the two needles.

Take a small section of graphite refill, place it on the line, and expertly draw an ellipse.

Then he drew a Cartesian coordinate system in the center of the ellipse, wrote a standard formula for the ellipse in the coordinate system, and explained it a little with the Pythagorean theorem, and Lin Xi understood it.

"You see, it's an ellipse, it's not perfect as you say, it looks weird. Why weird? Because the long axis and the short axis are not the same length. ”

Chen Jian drew a circle with a needle and thread on the side, and also wrote the Cartesian coordinates, and next to this circle, he still wrote a standard formula for an ellipse.

Lin Xi looked at it for a while, and vaguely understood something, but he couldn't grasp it.

Chen Jian reminded that the major and minor axes of the ellipse were the same, so the formula that should have been an ellipse was drawn as a circle.

So, if you think the definition of a circle is perfect, then an ellipse naturally doesn't look perfect. If you think of a circle as an ellipse, then the circle is just an ellipse with a minor axis and a major axis. In other words, even if it looks ugly, there is actually a perfect set of rules inside, and the circle is just a special existence within this rule. ”

"You look at an ellipse by the rules of a circle, and of course it's not perfect. But if you look at the circle according to the rules of the ellipse, it is perfect. ”

"Since circles and ellipses are like this, isn't there a rule that we don't know about the strange plants, trees, fish, and insects in this heaven and earth that determines that they grow like this? This rule must be perfect, but the variety displayed under the rules is not perfect. The perfect rule itself is also a kind of perfection. ”

Jian Chen blinked his eyes and encouraged, "Perhaps, you should find a way to find a perfect way to explain the diversity and strangeness of species to explain this colorful world." I still believe that the rules of the world itself are perfect. ”

Lin Xi stared blankly at the circles and ellipses on the paper, thinking about the perfect rule, and felt more and more reasonable.

Chen Jian stood up, pointed to the vegetable garden outside, and said: "Just like the green insects in the vegetable garden outside, I guessed it, maybe they were originally colorful, but maybe the green ones can be hidden on the vegetable leaves from being discovered by birds; The colored ones are easy to be eaten by birds. ”

"Or many colorful green insects that are messy and excessive, because they violate a certain rule between heaven and earth, so they can only be green. Green seems to have no reason, but in fact, it may be the most compliant. I think that since the world exists, then there must be perfect rules that shape the world, then everything is perfect and in accordance with the rules, and the imperfect that does not conform to the rules is dead. ”

"It's just that we haven't found out about this rule yet, so it looks chaotic and irrelevant."

"Do what you want, don't go beyond the rules. This is true of people, and so are things. ”
